Advaita Vedanta — Non-Dualism
The sub-school of overview-vedanta that holds reality is non-dual: there is only one ultimate existence (Brahman), and the apparent multiplicity of selves, objects, and worlds is a misperception (maya). The most influential interpretive framework of the Upanishads, systematized by Adi Shankara (~788-820 CE) and the lineage descending from him.
Advaita = a- (not) + dvaita (two). “Not-two”.
The Single Central Claim
Brahman is the only reality. Atman (the apparent individual self) is identical to Brahman. The world appears to have multiplicity but doesn’t, ultimately, have it.
The Upanishadic mahavakyas (“great statements”) condense this:
- Tat tvam asi (“That thou art”) — Chandogya Upanishad
- Aham brahmasmi (“I am Brahman”) — Brihadaranyaka Upanishad
- Prajnanam brahma (“Consciousness is Brahman”) — Aitareya Upanishad
- Ayam atma brahma (“This self is Brahman”) — Mandukya Upanishad
Why Maya Isn’t Illusion (Be Careful Here)
The popular framing “Advaita says the world is illusion” is wrong by simplification. Shankara’s actual claim is more careful: the world has vyavaharika (transactional/empirical) reality but not paramarthika (absolute/ontological) reality.
- The rope in the dim light appears to be a snake. You react to the snake.
- Once light comes, the snake never was — but the rope was always there.
- The snake had transactional reality (your heart rate spiked) but no absolute reality.
Maya is what makes Brahman appear as the manifold world. Not non-existent. Just not what it appears to be.
The Liberation Mechanism
In Advaita, moksha (liberation) is not acquired — it’s recognized. You were always Brahman; you just didn’t know it. The misperception (avidya, ignorance) drops; that’s it.
This makes Advaita’s path jnana yoga (the path of knowledge/inquiry) — distinct from:
- Bhakti yoga (devotion) — the path the dualist schools favor
- Karma yoga (action without attachment to fruit)
- Raja yoga (meditation) — Patanjali’s path
A serious Advaitin practices all four; jnana is the culmination.
Shankara’s Method: Adhyaropa-Apavada
A two-step pedagogical structure:
- Adhyaropa (“superimposition”) — Teach the student about a Brahman with attributes, world, jiva (individual soul), devotion. Easy entry.
- Apavada (“removal”) — Once the student is anchored, dismantle the constructed structure. Brahman has no attributes; jiva was never separate; the world wasn’t real in the way they thought.
This is upaya (skillful means) — a Buddhist concept Advaita echoes.
The Three States Argument (Mandukya Upanishad)
The most rigorous Advaita proof-of-concept:
- Waking state (jagrat) — gross objects, “you” experience them
- Dream state (svapna) — subtle objects in mind, “you” experience them
- Deep sleep state (sushupti) — no objects, but you wake up saying “I slept well, I knew nothing” — something witnessed the no-knowing
- Turiya (the fourth) — the witness common to all three states. THAT is the Atman. THAT is Brahman.
Identifying with the waking-state body-mind is identifying with the smallest of the four. The witness is the deeper invariant.
The Critics Within Vedanta
Ramanuja (Vishishtadvaita) and Madhva (Dvaita) are not in disagreement about the Upanishads being valid. They disagree with Advaita’s interpretation:
- Ramanuja: souls and world are real, but Brahman’s body. Devotion to Vishnu is the path; you don’t dissolve into Brahman, you serve Him forever in liberation.
- Madhva: Brahman, souls, world are eternally distinct. Hierarchical pluralism.
The same Upanishadic verses are read differently. None of the three reads is obviously textual nonsense; each has 1000+ years of commentary defending it.
Why Advaita Dominates Modern Western Hindu Discourse
Two reasons:
- Vivekananda’s Chicago 1893 speech + subsequent Western tours framed Hinduism as Advaita-flavored to Western audiences. Vedanta Society of New York (founded 1894) carried it forward.
- Advaita translates into Western philosophical idiom more cleanly than the dualist schools. Comparison with Plotinus, Spinoza, Buddhism is easier.
Within India, the dualist and qualified-dualist schools have larger lay populations. Advaita is overrepresented in elite/academic discourse.
